This invention relates to improvements in clips for rope-way cars andthe like, and has for its object to provide a clip which willgrip therope with suflicient force to prevent the carfrom sliding, no matterwhat may be the inclination of the rope.

Aswill be more particularly described in connection with theaccompanying drawings, the clip may comprise, in its preferred form, a'hook bar to which the car or load is attached and ofwhich the upperportion is preferably formed into an annular ring provided with astation landing device including a carriage and wheels for use when thecar and clip are at rest, a suspension cylinder attached to the bottomportion of the inner side of the annular ring and extending verticallyinward therefrom, a suspension rod slidably mounted in the suspensioncylinder, a clevis axle and sleeve pivotally mounted upon the suspensioncylinder, a lever arm or pair of lever arms actuated by the clevis axleand sleeve, a horizontal shaft carried by the suspension rod, a wing rodslidably mounted in a wing cylinder which is perpendicular to thehorizontal shaft and a pair of pivoted jaws one of which issubstantially stationary and is integral with a wing and the other ofwhich is movable about their common pivot and is actuated by said leverarm or arms so as to grip the hauling rope when the car and clip aresuspended therefrom, and to release th'ehauling rope when car and clipare in a station.

The details of the clip as arranged according to this invention willnowbe described more particularly with reference to, the accompanyingdrawings.

Figures 6, 7 and 8 are front, side and plan views of the clip applied toa double rope system.

Referring now more particularly to the drawings, as shown in Figures 1tot, the

wing 2 is arrangedto fit along the upper side wing pin Swhich passesthrough the wing center Y; Y is apoint on the line of intersection oftheplane of the hauling rope 1 and the plane perpendicular to the wing2. The

wing 2 and a pairof lever arms6 are piv-' otally connected by the headpin 5 which passes through the wing center Y and is parallel to the wing2. The haulingrope 1 is gripped by the co-operation of the movable jaw 7which is integral with the lever arms 6 and the stationary jaw 8 whichis integral with the wing 2. R

B is a point on the axis of the sleeve 9 which is set in an inclinedposition in the plane of the. suspension rod 20 and which extends to thesuspensioncenter O. C is a point on theline of intersection of the planeof the hauling rope and that of the suspension rod 20, both setvertically and intersecting at right angles. At the center B there isarranged the cross bearing 12 which receives the tail axle 10and-intermediate axle 11 per pendicular to the axle 10. The tail axle 10is arranged at the tail end of the lever arm 6, and is parallel to thepin 5. A clevis memher-13 is pivoted by means of the intermediate axle11 to the cross bearing 12 and a clevis axle 14 is rotatably mounted inthe sleeve 9.

Both ends of thebifurcated member. 15 which projects from the sleeve 9are pivotally connected tothe projection 17 of the suspension cylinder16 by means of the pin 18 perpendicular to the plane of the suspensionrod, so that the clevis axle 14 will swing vertically.

The suspension rod 20 is integral with the horizontal shaft 21 and isslidably inserted into the suspension cylinder 16 and prevented fromrevolvingtherein by rneans of the key 19. The shaft 21 carries the axle22 which is perpendicular to the plane of the hauling rope 1. The sleeve23 mounted on the axle 22 is provided with the downwardly extending wingrod 24, which is slidably inserted-into the wing cylinder 4. Rotationalmovement cylinder 16 (Figure 2) thereof is prevented by the key 25,provided on the inner surface of the cylinder. The sleeve 23 is fixed onthe axle 22 by means of the nut 26.

The clip includes, in addition to the fore going elements, an annularring 35, (Figures 1 and 4) having the suspension cylinder 16 projectinginwardly from the lower portion foregoing description, but may bebriefly described as follows. Suppose the car is at rest at a-station,and its weight is supported from .the rails 32 (Figure4) There is arigid connection from the wheels 33 through the member 36,- the annularring 35 and the hook bar .37, to the receptacle or load.

The jaws 7 and 8 will be opened, since the spring S will contract andswing the sleeve 9 downwardly into a substantially horizontal position(Figure The lever arms 6 are thus operated to swing the jaw 7 awayfromthe aw 8, about their common pivot 5.. It now being desired to setthe car in motion, it is pushed along the rail 32 until the end of thewing 2 meets the moving hauling rope 1. The apparatus will then rotateabout the pivots '22 and 14 until the clip lies wholly along the upperside of the hauling rope, whatever may be the inclination oft-he latter.The hauling rope, because of its tension, will then exert an upwardpressure upon the wing 2 and consequently upon the jaws -7 and 8. Thiswill telescope the wing cylinder4 along the wing rod 24 (Figure 5) andwill soon slide the suspension rod 20 increasingly farther out of thesuspension The result is that the pivot 18 of the bifurcated member 15moves downward in relation to the horizontal shaft 21, and'approachesthe jaw pivot 5, (see Figure 2). This relative movement of thesuspension cylinder 16 and suspension rod 20 operates to rotate thelever arms 6 about the pivot 5 by means of the sleeve 9 and bifurcatedmember 15, which are brought to an inclined position (Figure 2). The jaw7 is thus made to approach the jaw 8, and the hauling rope 1 is grippedbetween them. lVhenthe car comes to a station the weight is taken by thewheels 33; the hauling rope no longer exerts an upward pressure; and thereverse operation takesplace, so that the jaws cease to grip thehaulingrope.

Clips of the foregoing type are to be utilized in the single ropesystem, while clips of the type shown in Figures 6 to 8 are for use inthe double rope system. In the double rope system the construction ofthe wing is varied. In order to cover the carrying rope indirectly, thewing 2, carried by the wing pin 3 and jaw pin 5, is shortened and isprovided with a pair of suspension levers 28 which are perpendicular tothe wing 2, and

which extend upwardly in a plane perpendicular to the wing. The upperends of the suspension levers '28 are rigidly, connected to the maincarriage 29, parallel to the pin 5. A pair of wheels, 30, are arrangedon each side of the-main carriage 29 and rotate on the carrying ropewhich. is stretched parallel to and over the haulingrope. The wheels maybe held either directly by the main carriage, orindirectly by theauxiliary carriage 31, so that the length of the main carriage willcorrespond to that of the wing in the single rope system, therebykeeping the clip in equilibrlum.

As above 'mentionedin connection with the description of clips for useon the single rope system, in ayciip arranged for use on the double ropesystem the carriage and wheels which move on the carrying rope of thedouble rope way system form a part of the clip. The upper portion of thehook bar '37 is formed into the annular ring 35, from the bottom ofwhich extends vertically the suspension cylinder 16. The'top of the ringis formed into the arm 36 on which is arranged the carriage 34 forsupporting the wheels 33.

lVhen the car suspended upon the hauling rope proceeds into a stationsafely, if the auxiliary wheel- 33 is caused to revolve upon thesuspension-rail 32 arranged in the station, the "distance between thehauling rope 1 and the suspension rail is progressively increased andthe suspension center C will be raised so that while the sleeve9 is madeto lie horizontal, the movable jaw 7 is thrown out of the grippingposition, and the'hauling rope 1 will be disengaged or released.

The car which once disengages the hauling rope 1 runs on the rail in thestation, and when it is to be started again,in the single rope system,it is only necessary to move the end of the wing '2 into contact withthe hauling rope 1, and by the inertia of propulsion the total length ofthe wing covers the hauling rope. Similarly in the double rope system,the main carriage 29 of the wheel 30 is parallel to the carrying rope27, and upon gripping the hauling rope in the clearance between the twojaws compresses the lever arm 6 upwardly.

The mechanism of the clip according to this invention superior to othersis the suspension rod 20 and wing rod 24 engaged by the shaft 21 andaxle 22. These rods are like a compass in the front View and like aclamp in the side view. These rods are inserted into respectivecylinders and kept from revolving by means of keys. The suspension rodis operated by the load to be ap lied to the suspension hook .37 andkept a ways vertical notwithstanding the variation of the inclination ofthe hauling rope.
